Each day, Luko turns that plan into a workout built for where you are now. It’s 100% personalized training just for you — not just another list of exercises. LOG MEALS IN SECONDS Snap a photo, describe what you ate, or type it in. Luko estimates calories and macros. Need inspiration? Find recipe ideas with Luko when you’re not sure what to eat next. TURN HEALTHY DAYS INTO A COLLECTION Luko is built to make progress feel visible. Log meals and complete workouts to unlock animal companions across collectible sticker maps.

A BUDDY, NOT A MEDICAL DEVICE Calorie, macro, and workout estimates are for general wellness purposes and may not be exact. Luko is not a medical device and does not replace professional medical advice. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
